From c682514a8f17a886f31c5aa0bba78c4f260fbfcf Mon Sep 17 00:00:00 2001 From: Mans Rullgard Date: Tue, 11 Oct 2011 17:45:55 +0100 Subject: [PATCH] qdm2: fix signed multiplication overflow This code relies on the result wrapping as for unsigned values, and the sign is not used. Thus an unsigned type is proper here.
